Intermittent hot water.Changed diverter valve,heat exchanger,fan, PCB. Vaillant turbomax 282e But still no hot water.


Sounds like you need a new Thermo coupler.
Could be as simple as a dirty pilot and needs cleaning but I suspect a thermo coupler.

Vaillant boiler leaking only when heating switched off.


It would seem a joint has come a bit loose from the heating and cooling cycle. put a drip pan under the leaking area( the drips would evaporate quickly), then next time you shut it down go through all the joints in the area with wrenches to find the loose joint.

Vaillant Boiler 628 suppling no Central Heating


If the zone valve was replaced and wired correctly then it is likely the zone controller if u have one. Manually open the valve and turn the tstat up if it begins to circulate then it is a controller issue. If you still get no heat (circulation) than it is the circulator pump or the pumps controller. Its best to test those individual parts with a multimeter to avoid buying parts not needed

Vaillant turbomax 28 constant hot water problem.


got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps
